"A user scrolling the page will find at some point that their mouse has come over a map which is now eating the scroll events and they are now scrolling the map instead." This annoyance has been widely extant for ten years or more - I think I first experienced it with google maps as I believe they were the first to zoom with scroll ... Seems easy to fix - sub window elements in the browser cannot zoom until clicked on ? It's amazing that behavior made it through one browser version iteration.
